Technical Field

[0001] The utility model relates to the technical field of rotary kiln gear lubrication, in particular to a kiln gear lubrication oil heating device. Background Art

[0002] The rotary kiln needs lubricating oil for both large and small gears, and the gear lubricating oil has high viscosity. In order to smoothly extract and transport it from the oil drum, it is generally heated and kept at about 40°C. For example, the Chinese utility model patent "A jet lubrication system, publication number CN220601186U" has an oil drum heating device wrapped around the outer circumference of the oil drum to achieve heating of the oil drum. Generally, the width of the heating device is fixed and it is difficult to replace. Utility Model Content

[0003] The invention purpose of the utility model is to provide a kiln large and small gear lubricating oil heating device for the above-mentioned problem, which can realize rapid disassembly and assembly.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is:

[0005] A kiln large and small gear lubricating oil heating device comprises a controller and a heating blanket. The front of the heating blanket can be wrapped around the outer circumference of an oil barrel. The heating blanket is connected to a controller to achieve heating control. It also comprises a locking assembly. The circumferential ends of the heating blanket are detachably connected by at least two locking assemblies, and the at least two locking assemblies are evenly distributed along the axial direction.

[0006] The lock assembly includes a lock hook, a hanging ear, and a spring. The lock hook and the hanging ear are respectively installed at both ends of the back of the heating blanket. The I end of the spring is connected to the hanging ear, and the II end of the spring can be stretched and buckled on the lock hook under the action of external force. A hanging hole is opened on the hanging ear, and the I end of the spring is connected to the hanging hole, which can be quickly passed through for hanging and prevents it from falling when disassembling.

[0007] As mentioned above, the two ends of the heating blanket are detachably buckled by at least two locking components, which can realize quick disassembly and assembly. At the same time, the spring is used for buckling, and it can be pressed tightly on the oil drum within a certain circumferential width range, thereby increasing the applicable range of the oil drum size.

[0008] Based on the foregoing solution, in an improved solution, to solve the heat insulation problem when arranging the controller on the heating blanket, the heating device further includes cushion blocks. At least two cushion blocks are arranged at the middle position on the back of the heating blanket, and the cushion blocks are arranged to extend axially. The controller is installed on the back of the cushion blocks. Arranging the controller on the heating blanket facilitates on-site temperature control adjustment. Heat insulation is achieved by separating with cushion blocks. The cushion blocks on the heating blanket extend vertically (axially), which is conducive to convective heat dissipation. In a preferred solution, the heating device further includes a backing plate. The front of the backing plate is installed on the back of the cushion blocks, and the controller is installed on the back of the backing plate. Separating with the backing plate between the cushion blocks and the controller further improves the heat insulation effect.

[0009] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0010] For a large and small gear lubricating oil heating device of the utility model, the circumferential two ends of the heating blanket are detachably buckled through at least two buckle assemblies, which can realize quick disassembly and assembly. At the same time, a spring is used for buckling, which can be tightly pressed on the oil barrel within a certain circumferential width range, and basically does not affect the heating effect, improving the applicable range of the oil barrel size. Heat insulation is achieved by separating with cushion blocks and a backing plate. The cushion blocks on the heating blanket extend vertically (axially), which is conducive to convective heat dissipation. Description of the Drawings

[0019] Embodiment 1

[0020] See also Figures 1-7 A kiln large and small gear lubricating oil heating device of this embodiment includes a controller 3 and a heating blanket 1. The front of the heating blanket 1 can be wrapped around the outer periphery of the oil barrel 100. The heating blanket 1 is configured to be connected to the controller 3 to achieve heating control; it also includes a locking assembly. The circumferential ends of the heating blanket 1 are detachably connected by at least two locking assemblies, and the at least two locking assemblies are evenly distributed along the axial direction.

[0021] Among them, the heating blanket is rolled and pressed on the outer circumference of the oil drum in the rolled state, the circumferential direction of the oil drum is the circumferential direction, and the central axis direction of the oil drum is the axial direction. When the oil drum is installed horizontally, the axial direction is the vertical direction. The connection and control of the heating blanket 1 and the controller 3 are both existing technologies. The controller 3 is connected to the mains through an external cable, and is also connected to the positive and negative terminals 31 and 32 of the heating blanket through an internal cable, which will not be repeated here. The present application is to apply the heating blanket to the rotary kiln gear lubricating oil drum, and to improve the heating blanket rolling connection and controller installation structure. This embodiment 1 is explained by taking the example of 6 locking components evenly arranged on the axis.

[0022] The lock assembly can be a fixed position circumference buckle component, such as a lock hook buckled on the hanging hole of the hanging ear, such as a strap to bind the lock hook and the hanging ear. The present application preferably adopts an adjustable circumference lock assembly structure, which includes a lock hook 22, a hanging ear 21, and a spring 2. The lock hook 22 and the hanging ear 21 are respectively installed at both ends of the back circumference of the heating blanket 1. The I end of the spring 2 is connected to the hanging ear 21, and the II end of the spring 2 can be stretched and buckled on the lock hook 22 under the action of external force. A hanging hole is opened on the hanging ear 21, and the I end of the spring 2 is inserted and connected to the hanging hole, which can be quickly passed through for hanging, and plays a role in preventing it from falling during disassembly.

[0023] As mentioned above, when in use, the front side (heating surface) of the heating blanket is wrapped around the outer circumference of the oil drum, and then the spring hung on the hanging ear is tightened and buckled on the lock hook. Moreover, for example, the circumferential length of the heating blanket is 200 cm (relative to the circumference of the oil drum) and the axial length is 80 cm (relative to the height of the oil drum). When the two circumferential end faces of the heating blanket are in contact, the spring can be tightened and buckled between the hanging ear and the lock hook, and the spring can also be pulled outward by 15 cm. When the distance between the two circumferential end faces of the heating blanket (exposed width) is less than 10 cm, the heating effect of the oil drum is very small. At this time, the applicable circumference of the oil drum is 200 cm-215 cm, and the applicable circumference of the oil drum with basically the same heating effect is 200 cm-210 cm; if the two ends of the heating blanket can cover each other by a width of less than 10 cm, the applicable circumference of the oil drum is 190 cm-215 cm, and the applicable circumference of the oil drum with basically the same heating effect is 190 cm-210 cm.

[0024] In this way, the two ends of the heating blanket are detachably buckled by at least two locking components, which can achieve quick disassembly and assembly. At the same time, the spring is used for buckling, and it can be pressed tightly on the oil drum within a certain circumferential width range without affecting the heating effect, thereby increasing the applicable range of the oil drum size.

[0025] Example 2

[0026] See also Figures 1-7 A kiln large and small gear lubricating oil heating device of this embodiment includes a controller 3 and a heating blanket 1. The front of the heating blanket 1 can be wrapped around the outer periphery of the oil barrel 100. The heating blanket 1 is configured to be connected to the controller 3 to achieve heating control; it also includes a locking assembly. The circumferential ends of the heating blanket 1 are detachably connected by at least two locking assemblies, and the at least two locking assemblies are evenly distributed along the axial direction.

[0027] Here, an example of 6 lock components evenly arranged on the axis is used for explanation. The lock component includes a lock hook 22, a lifting ear 21, and a spring 2. The lock hook 22 and the lifting ear 21 are respectively installed at both ends of the back side of the heating blanket 1. The I end of the spring 2 is connected to the lifting ear 21, and the II end of the spring 2 can be stretched and buckled to the lock hook 22 under the action of external force. A hanging hole is opened on the lifting ear 21, and the I end of the spring 2 is connected to the hanging hole, which can be quickly passed through for hanging, and it also prevents it from falling when disassembling.

[0028] In order to solve the problem of heat insulation when arranging the controller on the heating blanket, the heating device also includes a pad 4, at least two pads 4 are arranged in the middle of the back of the heating blanket 1, and the pads 4 are arranged in an axially extending manner, and a controller 3 is installed on the back of the pads 4. Among them, this embodiment is described by taking the axial extension arrangement of two pads (for example, the length, width and height of the pads are 8cm*2cm*2cm and 4cm apart) as an example. The pads can be made of plastic blocks with low thermal conductivity; thermal insulation cotton blocks can also be used, connected with viscose, and also have a buffering effect. The controller (for example, the length and width are 11cm*11cm) is arranged on the heating blanket, which is conducive to on-site temperature control and adjustment. The pads are separated to achieve heat insulation. The pads are arranged vertically (axially) on the heating blanket, which is conducive to convection heat dissipation.

[0029] As mentioned above, when in use, the front side (heating surface) of the heating blanket is wrapped around the outer circumference of the oil drum, and then the spring hung on the hanging ear is tightened and buckled on the lock hook. In this way, the circumferential ends of the heating blanket are detachably buckled through at least two buckle components, which can achieve quick disassembly and assembly. At the same time, the spring is used for buckling, and it can be pressed tightly on the oil drum within a certain circumferential width range, which does not affect the heat conduction effect and increases the applicable range of the oil drum size.

[0030] Based on the foregoing examples, in a preferred example, the heating device further includes a backing plate 41. The front surface of the backing plate 41 is mounted on the back surface of the spacer block 4, and a controller 3 is mounted on the back surface of the backing plate 41. A backing plate (for example, the length, width, and thickness of the backing plate are 8 cm * 8 cm * 2 cm) is used to separate the spacer block from the controller, further improving the heat insulation effect.

[0031] It should be noted that the examples of the above embodiments can be preferably selected one or more than two in combination according to actual needs. The accompanying drawings of a set of combined technical features are used for multiple examples, and will not be elaborated one by one here.
